This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation or deflagration of the emulsion causing fatal injuries and generation of toxic NOx gases. Increase in economically and safely extractable deep-level ore volume that generates greater export earnings and more jobs are expected project outcomes, as is reduced atmospheric pollution.

本项目旨在开发一种新型乳化炸药，该炸药不受极深矿中高温和活性岩石条件的影响。这些乳化液将包含一个可调节的聚合物网络，以防止乳化液柱在高温矿山的热孔中坍塌，并添加添加剂以消除与岩石的放热反应。如果不加以阻止，该反应会引起乳化液的过早爆轰或爆燃，造成致命的伤害和产生有毒的氮氧化物气体。预计项目成果将增加经济、安全可开采的深层矿石量，从而产生更大的出口收入和更多的就业机会，同时减少大气污染。
